Pervious Concrete Contractor
Certification Program

Program Summary

The
goal of this certification program is to ensure that knowledgeable
contractors are selected to place the product and thereby minimize the chance
for failure.

The program is designed to be administered locally by
local sponsoring groups in conjunction with planned training sessions or
demonstrations of pervious concrete placement. NRMCA provides
certification exams and performance evaluations to approved local sponsoring groups for administering the
certification. For the current list of local sponsoring groups,

Three
levels of certification are available:

A Pervious Concrete Technician is a person who
demonstrated knowledge about proper procedures to place, compact, finish,
edge, joint, cure and protect pervious concrete pavements, but who lacks the
requisite field experience to qualify as a pervious concrete Installer or
Craftsman.

A Pervious Concrete Installer is a person who has
demonstrated the ability to place, compact, finish, edge, joint, cure and
protect pervious concrete pavements and has documented a limited
project-based field experience in placing pervious concrete.

A Pervious Concrete Craftsman is a person who has
demonstrated the ability to place, compact, finish, edge, joint, cure and
protect pervious concrete pavements and has documented a higher level of
field time-based experience in placing pervious concrete.

Scope and Knowledge

The program requires knowledge
in the following areas of concrete construction:

NRMCA Pervious
Concrete Contractor Certifications shall be valid for a period of five [5]
years. The expiration date for the certification shall be based on the date of completion of the written examination.

Exam Information

The two-hour written
examination is "closed book," consisting of approximately 50
multiple-choice questions. The passing grade for the written examination is 75%

During the performance
evaluation, each examinee must demonstrate procedures for placing,
compacting, finishing, edging, jointing and beginning curing a pervious
concrete slab. The examiner will observe and evaluate the techniques used and
record passing or failing grades on the various individual procedures. A passing
grade is defined as "no significant variation from proper procedure and no more
than two variations from proper technique in the use of the tools."

The project experience or work experience must
include placing, consolidation, finishing, edging, jointing and curing of
pervious concrete and must be documented on the Installer Application form or
the Craftsman Application.

Recertification

Recertification is required every
five years and requires successful completion of a written examination.
